Assembly having two copper sheets screwed to each other and method for producing said assembly

Abstract

The invention relates to an assembly comprising two copper sheets, which are connected to each other by means of a screw connection, wherein the screw has been screwed directly into the copper sheets without screw holes having been provided, and to a method for producing said assembly.

Description

Background technique [0001] In the field of automotive electrical and automotive electronics, in particular in conjunction with the electrification of motor vehicles, more and more consumer goods are used which require high currents for operation. In order to keep losses as low as possible, the necessary electrical conductors must have only a small resistance. This can be achieved on the one hand by means of a correspondingly large cross-section, which is expensive due to the correspondingly high material outlay, or on the other hand by means of a correspondingly high electrical conductivity. In this context, copper remains the preferred choice due to its properties in this regard. These conductors, commonly called busbars, are generally made of copper sheets and must be connected to each other or also to other objects made of copper, such as press-in pins. For this, connection methods such as riveting, soldering or welding can be considered, although the high thermal conduc...
